NestJS is not limited to monolithic HTTP servers. Its microservices package lets teams split applications into independent services that communicate via message brokers, Redis, or gRPC — ideal for high-scale platforms.
Transport Layers
NestJS supports multiple transports: TCP for simple service-to-service calls, Redis for pub/sub, RabbitMQ and Kafka for reliable queues, MQTT for IoT, and gRPC for high-performance RPC between services.
Message Patterns and Event Bus
@MessagePattern() handles request-response flows, while @EventPattern() supports fire-and-forget events. This makes it easy to build order processing, notification, and analytics pipelines.
Hybrid Applications
A single NestJS app can run both HTTP REST endpoints and microservice listeners — useful during migration from monolith to distributed architecture.
- TCP, Redis, RabbitMQ, Kafka, MQTT, and gRPC transports.
- Request-response and event-driven patterns.
- Hybrid monolith + microservice deployment.
- Service discovery and health checks.
- Scalable background job processing.
